Understanding Compound Interest
What is Compound Interest?
Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. It's often called "interest on interest" and is the key to wealth creation.
The Power of Compounding
Albert Einstein allegedly called compound interest the "eighth wonder of the world." The longer you invest, the more dramatic the compounding effect becomes, especially with regular contributions.
Formula
A = P(1 + r/n)^(nt)
Where: A = Final Amount, P = Principal, r = Rate, n = Compounding frequency, t = Time
